Hello, I want to learn how to solve this question. While
answering it please explain step by step and with
readable* writing. I sincerely appreciate the
assistance.
1.00x10-3 mol PCls is introduced into a 250 ml flask and equilibrium is established at 284 °C: PC1s(g) - PC13(g) + Cl2(g) The quantity of Cl2 present at equilibrium is found to be 9.65x10-4 mol. What is the value of Kc for the dissociation reaction at 284 °C?
Please explain thouroughly I want to understand how to answer these
three questions as well as answer to see what I’m doing wrong.
1. If you had 350 ml of a 2.5M aqueous solution of C2H,O what would you have to do to get the molarity of it to 1.8M? Be specific. (2) the following chemical teaction. (2) MgS (aq) + CuC, (aq) Cus (s)+MgCl, (oq) say what is being oxidized and reduced for the 2. Write the complete and...

Organic Chemistry question. Please show work, so I can learn how to solve the problem. Thanks! What quantity of 7.00 M aqueous H2SO4 (in mL) would be required to neutralize 817 mL of 3.00 M aqueous Ca(OH)2? Please carry maximum number of significant figures through to final answer then round to a whole number.
please i need help with these questions .. thanks so
much
A 24.5 mL sample of a 0.473 M aqueous nitrous acid solution is titrated with a 0.398 M aqueous sodium hydroxide solution. What is the pH at the start of the titration, before any sodium hydroxide has been added? pH = Submit Answer Retry Entire Group 4 more group attempts remaining A buffer solution is made that is 0.319 M in HNO2 and 0.319 M in KNO, If K,...
Please explain thoroughly and draw diagrams when necessary. I usually rate within 24 hours. The focal length of your Nikon camera lens is 70 mm. It is used for taking pictures of your friend who is 1.5 m tall. What is your friend's distance from the lens if the image just fills the 24-mm vertical dimension of the film?
this is for spherical coordinates, please help explain
thoroughly because i dont know what this keans and thsnk you so
much i will rate up when i can!

thank you!
8. Without resorting to tables, state whether Sincreases, decreases or remains approximately the same for the following reactions/processes, and explain your rationale (check to make sure the equations are balanced, when relevant): a) H20 (1) H2O (g) b) 12 (g) + Cl2 (g) → 2 ICI (g) c) CO2 (g) → CO2 (s) d) raw egg → hard boiled egg e) mowing the lawn...
